Wiring module and power storage module

Abstract

A wiring module 20 includes: a flexible substrate 30 provided with a mounting portion 32 , a relay portion 33 that is continuous with the mounting portion 32 , and conductive paths 42 and 43 including a connection land 43 A disposed on the relay portion 33 ; a temperature measurement element 50 mounted on the mounting portion 32 ; a reinforcement member 60 disposed along the mounting portion 32 and the relay portion 33 and fixed to the mounting portion 32 ; a conductive busbar 70 connected to the electrode terminals 12 and 13 ; and a conductive relay member 80 that electrically connects the connection land 43 A and the busbar 70 to each other, in which the relay member 80 includes a relay base portion 81 connected to the busbar 70 , and a plate spring portion 82 that is continuous with the relay base portion 81 , overlaps the relay portion 33 and is electrically connected to the connection land 43 A, and biases the reinforcement member 60 toward the temperature measurement surface 11 F.

1 . A wiring module to be attached to a power storage element provided with an electrode terminal and having a temperature measurement surface, the wiring module comprising:
 a flexible substrate provided with a mounting portion, a relay portion that is continuous with the mounting portion, and a conductive path including a connection land disposed on the relay portion;   a temperature measurement element mounted on the mounting portion;   a reinforcement member disposed along the mounting portion and the relay portion and fixed to the mounting portion;   a conductive connection member connected to the electrode terminal; and   a conductive relay member that electrically connects the connection land and the connection member to each other,   wherein the relay member includes   a relay base portion connected to the connection member, and   a plate spring portion that is continuous with the relay base portion, overlaps the relay portion and is electrically connected to the connection land, and biases the reinforcement member toward the temperature measurement surface.   
     
     
         2 . A power storage module comprising:
 a power storage element provided with an electrode terminal and having a temperature measurement surface; and   a wiring module attached to the power storage element,   wherein the wiring module includes   a flexible substrate provided with a mounting portion, a relay portion that is continuous with the mounting portion, and a conductive path including a connection land disposed on the relay portion,   a temperature measurement element mounted on the mounting portion,   a reinforcement member disposed along the mounting portion and the relay portion and fixed to the mounting portion,   a conductive connection member connected to the electrode terminal, and   a conductive relay member that electrically connects the connection land and the connection member to each other,   wherein the relay member includes   a relay base portion connected to the connection member, and   a plate spring portion that is continuous with the relay base portion, overlaps the relay portion and is electrically connected to the connection land, and biases the reinforcement member toward the temperature measurement surface.
